Abstract
A composite is provided having an electrically conducting Al matrix and elongated filaments comprising Ca and/or Sr and/or Ba disposed in the matrix and extending along a longitudinal axis of the composite. The filaments initially comprise Ca and/or Sr and/or Ba metal or alloy and then may be reacted with the Al matrix to form a strengthening intermetallic compound comprising Al and Ca and/or Sr and/or Ba. The composite is useful as a long-distance, high voltage power transmission conductor.
Claims35
A metal-metal composite having an electrically conducting matrix comprising aluminum and having elongated metal filaments comprising an alkaline earth metal selected from the group consisting of Ca, Sr, and Ba disposed in the matrix extending along a longitudinal axis of the composite.
A metal-intermetallic composite having an electrically conducting matrix comprising aluminum and having elongated intermetallic compound filaments comprising Al and at least one of Ca, Sr, and Ba disposed in the matrix extending along a longitudinal axis of the composite.
An electric power transmission conductor comprising a metal-metal composite having an electrically conducting matrix comprising aluminum and having elongated metal filaments comprising an alkaline earth metal selected from the group consisting of Ca, Sr, and Ba disposed in the matrix extending along a longitudinal axis of the composite.
An electric power transmission conductor comprising a metal-intermetallic composite having an electrically conducting matrix comprising aluminum and having elongated intermetallic compound filaments comprising Al and at least one of Ca, Sr, and Ba disposed in the matrix extending along a longitudinal axis of the composite.
A method for making a metal-metal composite, comprising forming a mass having deformable components comprising Al and having deformable metal components comprising an alkaline earth metal selected from the group consisting of Ca, Sr, and Ba and mechanically co-deforming the components of the mass to form elongated metal filaments comprising the alkaline earth metal disposed in a matrix comprising Al and aligned along a longitudinal axis of the composite.
